DataPager

Here is the design of my page:

I have a TreeView; selecting a node in the view will display a ListView that is filled based on the node.

I also have a search function that displays the ListView filled based on the results of search.

Those functions both work correctly.

My ListView contains a DataPager. The DataPager initializes correctly and matches the contents of the ListView.

My problem is that I can't page. The DataPager itself is changed (page number, etc) but the ListView is static.

RadAjaxManager section

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

Hello Tony,

Could you please let me know if the application works correctly when the Ajax is disabled on the page.
Also I would suggest you to review the following online demo which provides approach for using RadDataPager with RadListView.
